SHORE Filed June 1o, 1948 Patented Oct. 25, 1949 UNITED STATES PATENTOFFICE Application June 10, 1948, Serial No. 32,191 In Sweden April 16,1948 2 Claims.

The invention relates to shores for use in building construction such asconcrete molds for yarches and other work, an object of the inventionbeing to provide improved means for this purpose comprising means foraccomplishing both major and iinal micrometric adjustment thereof toVary the length of the shore. Other objects and advantages will appearhereinafter or will be obvious.

The invention consists in the novel construction and combinations ofparts as hereinafter set forth in the claims.

In the accompanying drawings,

Figure 1 is a side View of the invention as applied.

Figure 2 is a front view of the same, and

Figure 3 is a section on the line 3 3, Figure 1.

In these drawings, the numeral I designates the base member of theshore, and 2 the adjustable member thereof, these members being each ofT- form in cross section with the heads thereof opposed to each other,ithe head of the base member being provided with gui-des 3 for andengaging the head of the adj ustabl-e member.

For the purpose of accomplishing major lengthwise adjustment of themember 2 with respect to the base member, a lever 4 is fulcrumed withina notch seat 5 of the flange of the base member, said lever beingprovided with a springurged pawl 6 engaging the ratchet teeth 'I of thefiange of the adjustable member.

For the purpose of accomplishing nal micrometric adjustment of themember 2 with respect to the lbase member, an eccentric device ismounted upon the upper end of the base member, said eccentric devicebeing provided with manipulable means for accomplishing such adjustmentdescribed as follows:

An annular strap 8 is iixed to the upper end of the base member I, acylindrical roller 9 being rotatably adjustable within said strap, saidroller having an aperture I 0 which is eccentric with respect to thecenter of said roller, manipulable means for accomplishing the rotatableadjustment of said roller Within said strap comprising a horizontal armI I Xedly secured to said roll-er within said aperture, said arm havinga handle end portion I2 at right angles thereto. A bail I3 depends fromand has its spaced ends pivotally engaging the opposite ends of said armII at opposite sides of the shore. the lower end of said 2 bail engagingthe ratchet teeth 'I of the ange of the adjustable member of the shore.

Thus rotative adjustment of said roll-er within said strap accomplisheseccentric adjustment of said horizontal arm I I with respect to saidroller and micrometric adjustment of said bail and of the adjustablemember of the shore, to vary the length of the shore. In order to fixthis micrometric adjustment a clamp bolt I4 has threaded engagement withthe ends of said strap, said bolt having a handle arm I5.

In order to center the shore with respect to the overlying work, twoangle irons I6 located side by side have each a vertical flange I1, ithetwo iianges rbeing spaced apart and engaging opposite sides of thesupport beam I8 of the mold for ith-e arch or other work, an underlyingfplate I9 supporting both angle irons, loop clamp 20 engaging over theadjacent ends of both angle irons and said plate, said angle irons beinglaterally adjustable to adjust the flanges thereof for work of varyingbreadths, and said loop clamp having a set screw 2| to fix theadjustment.

I claim:

1. In a shore, a base member, `a, member vadjustable lengthwise withrespect tothe base member to vary the length of the shore, and meansmounted upon the base member and engaging the adjustable member to:accomplish major lengthwise adjustment thereof and nal micrometriclengthwise adjustment thereof comprising ,a cylindrical strap fast tothe upper end of the base member, a cylindrical roller rotatable withinsaid strap yand having an eccentric aperture, a manipulable dew'cehaving a horizontal arm fixed to said roller 4within said aperture kanda bail depending from and one end of which is pivoted to said horizontalarm and the other end of which engages said adjustable member, saidstrap having manipulable means for closing the same upon said roller tofix the adjustment.

2. In a shore, a base member, |a member adjustable with respect to the:base member to vary the length of the shore, and means mounted upon thebase member and engaging the adjustable member to accomplish majorlengthwise adjustment thereof :and nal Ymicrometric adjustment thereofcomprising an eccentric device mounted upon lthe Iupper end of the basemember having manipulable means for accomplishing the eccentricadjustment thereof and for xing the -adjustment, the upper end of theadjustable member Ibeing provided with means for centering the shorewith respect to the overlying work comprising two angle irons locatedside by side and hav- 5 10 Number 4 for work of Varying breadths, andsaid loop clamp having a set screw to x the adjustment.
